Preparation, characterization, and photocatalytic activity of novel AgBr/ZIF-8 composites for water purification

Facile and Green Synthesis of Starfruit-Like ZIF-L, and Its Optimization Study

“…As shown in Figure 8 , the diffraction peaks of ZIF-L at the (110), (200), (211), (220), (310) and (222) planes were observed at 2θ values of 7.58°, 10.80°, 12.54°, 14.95°, 16.49° and 17.86°, respectively. This result had an excellent agreement with several reports from previous studies [ 14 , 20 , 28 , 34 , 39 ]. This proves that ZIF-L was successfully synthesized to have a high crystallinity.…”

“…They have a crystalline structure, large surface area, high pore volume, tunable pore size, good adsorption capacity, good thermal and chemical stability, and flexibility, and are easy to functionalize and modify [ 4 , 5 , 6 , 7 , 8 ]. Due to their outstanding characteristics, they have been applied in many applications, such as selective adsorption [ 9 , 10 , 11 ], water and wastewater treatments [ 12 , 13 , 14 ], composite constituents [ 15 , 16 ], catalysts and photocatalysts [ 17 , 18 ], fluorescence sensors [ 1 , 19 ], gas storage and separation [ 20 , 21 ], and drug delivery [ 22 , 23 ]. In the last few decades, many types of MOFs have been studied and developed through various synthesis methods, including diffusion, solvo(hydro)thermal, microwave, electrochemical, mechanochemical and sonochemical methods [ 24 ].…”

Mechanism insight into the photocatalytic degradation of fluoroquinolone antibiotics by the ZIF-8@Bi2MoO6 heterojunction

“…63 In brief, the porous structure of ZIF-8 in BIZ greatly improves the charge separation during photocatalysis, enhances the adsorption of reactants on its surface, provides a large number of active sites, and thus accelerates the photocatalytic reaction. 64,65…”

“…63 In brief, the porous structure of ZIF-8 in BIZ greatly improves the charge separation during photocatalysis, enhances the adsorption of reactants on its surface, provides a large number of active sites, and thus accelerates the photocatalytic reaction. 64,65 When combining Na 2 S 2 O 8 and visible light, the OFX treatment efficiency of the BIZ material increased from 26.36% to 96.36%, indicating the significant role of Na 2 S 2 O 8 in the photocatalytic degradation of OFX under visible light conditions via the formation of ROS (e.g., sulfate, hydroxyl, and superoxide radicals). These results clearly indicate that the BIZ photocatalyst can successfully and efficiently activate Na 2 S 2 O 8 for OFX degradation.…”

One-pot In Situ Microwave Hydrothermally Grown Zeolitic Imidazolate Framework-8 on ZnIn-Layered Double Oxides toward Enhanced Methylene Blue Photodegradation

“…39 ZIF-8 has a wide range of applications in heterogeneous catalysis, sensing, gas storage, 40 and photocatalysis. However, ZIF-8 has a wide band gap (∼5 eV), 41 small particle size, 42 and low electron discharge capacity, 43 which limits its practicability in the field of photocatalysis. A series of strategies were designed to modify and adjust the ZIF-8, such as adjusting organic ligands, metal semiconductors, and metal-free semiconductor doping with ZIF-8.…”
